This invention relates generally to lubricating systemsandv con'sists of certain novel features of construction, combinations and arrangements'of j-parts asywill be more fully described and particularly pointed outin the appended claims. j

In the accompanying drawing. I Figure l is afront elevation of a pump 'cas ing embodying my invention; v V l igure 2 is a top pl'an view thereof;

Figure 3 is a vertical sectional; view taken on the line 3,3vof. Figure 2;

v Figure 4 is a deta'l elevation of thebearing plate. which is attached to the crankcase.

Referring now to the drawing; in @which like characters oat-reference designate corresponding parts throughout theseveral views,

I the-numeral 1 designates atpu'mp casing that is preferably formed of an integral cylinder" 2 and a'crank case 3. Assho'wn, the crank case 3 is preferably providedat its lower end with. a removable pan 4 and has a detachable plate 5 at one side thereof-through which a suitable crank shaft 6 extends. This shaft also; extends through a ivertical. partitionsor baffle-'7 projecting downwardly from the lower end of the cylinder 2 and is ournalled in suitable bearings 8 and 9 respectively extending through the plate 5 and partition 7.

In order that a suitable lubricant such as 'oil, in the crank case may be supplied'to the bearings 8 and 9 and also to the outer surface of the crank pin 10 upon which the lower end of the connecting rod 11 is mounted, I preferably provide a suitable fly wheel 12 that is non-rotatably secured to the reduced inner end portion 13 of the crank shaft 6 and is provided upon opposite sides thereof with suitable radially extending grooves or re-' cesses 14 for picking up oil from the crank case and throwing it into a downwardly inclined trough 15 leading to a receptacle 0r. pocket 16 at one side of the crankcase. For conveying the oil from the receptacle tothe bearings and crank pin T preferably provide a short tube 17 that'communicates with a longitudinally extending bore 18 and the branch transversely extending bores 19 in the crank shaft 6. As shown, the tube 17 is preferaably journalled in a suitable bearing 20 extending through the inner wall 21 of the receptacle and threadedly engages the walls of a longitudinally extending socket 22 in the .inner end of the crank shaft 6. The short branch bores 19 in the crank shaft are preferably spaced theproper distance apart so that .15 orreceptacle16. r

Thus, t he centrifugally. thrown lubricant will be directed toward. the trough While a is believedfthat: am the forego Q,

ing'description the nature and advantages of the invention will .be readily apparent, I de sire to have it understood that I do not limit myself to what is herein shown and described,

and that such changes may be resorted to when desired as fall within the scope of what is claimed. s

v What I claim as my invention is 1. The combinationwitha crank case containing lubricant, of a rotatable crankshaft in said case having a longitudinally extending bore, a receptacle in the case, centrifugal means for transferring lubricant fro-m the crank case'to the receptacle, bearings for the crank shaft, and a tube positioned within said shaft and communicating with the longitudii nally extending passage therein for conveying lubricant from the receptacle to the longitudinally extending'bore in the shaft, said shaft having means for supplying lubricant from said longitudinally extending bore to said bearings. i

2. The combination with a crank case containing lubricant, of a rotatable crank shaft j.

in said case having a longitudinally-extendmg bore, a receptacle in the case, means for the receptacle, bearings'for the crank shaft,

7 transferringlubricant from the crank case to and aseparate tube arranged within said shaft and communicating at one end with the recep- .ta'cle and at the opposite end with the longi tudinally extending bore in the shaft for conveying lubricant from the receptacle to the longitudinally extendingjbore in the shaft,

said shaft having transversely extending passages for supplying lubricant from said longi-: A tudinally extending passag to said bearings.

3. The combination wit a crank case containing lubricant, of a partition in the case terminating short of the bottonrthereof, of a crankshaft extending through the partition and a. wall fofth e crankcase, said shaft havv ing a longitudinally extending bore, a receptacle in the crank case in communication w th the longitudinally extending bore in the shaft and adapted to contain a supplyof lubricant,

means for transferring the lubricant from the crank case to the receptacle, and bearings for said crank shaft, said shaft having means for receptacle in the crank casein communication with the'longitudinally extending bore in the shaft and ac apted to contain a supply of lu bricant, a flywheel mounted, on the crank shaft beltv veen the partition andthe receptacle having means for transferring lubricant from the crank case to the receptacle, and bearings for the crank shaft, said shaftv having passages for conveying lubricant fromfthe longitudinally extending bore to the said bearings.

' 5. The combination with a crank case containing lubricant, and a rotatable crank shaft in said case, of a receptacle in the crank case, 40 means for transferring lubricant from the a crank case to the receptacle, bearings for the crank shaft, a tube journalled in a Wall of the receptacle and detachably connected to th shaft for conveying lubricant from therecept tacle to thelongitudinally extending bore in the shaft, said shaft having means for conveying lubricant from said" longitudinally extending bore to said bearings. Q I

6. The combination with a crank case containing lubricant, of a partition in the crank case terminating short of the bottom there-Y of-,'a crank shaft extending through said partition and a Wall of said crank case, and'having a crank portion disposed between said partition and the adjacent wall of the crank case, a receptacle in the crankcase upon the opposite side of the partition, a fly Wheel nonrotatably mounted on the crank shaft between. i i

thepartition and the receptacle having means for transferring lubricant from the crank case to the receptacle, bearings for the crank shaft engaging thepartition and wall aforesaid of the crank case, a connecting rod mounted on the crank portion of the shaft, and means for conveying lubricant from the rceptac-le through the fly 'wheel and shaft to the bearingsand connecting rod;

In testimony whereof I affix my signature.
